The airworthiness directive
47-47-02 PIPER: (Was Mandatory Note 6 of AD-780-3.) Applies to PA-12 Aircraft Serial Numbers 12-1 to 12-796 Inclusive, 12-815, 12-817 to 12-822 Inclusive, 12-825 to 12-831 Inclusive, 12-833, 12-835 to 12-848 Inclusive, 12-863 to 12-893 Inclusive, 12-895 to 12-901 Inclusive.
Compliance required as soon as practicable but not later than January 15, 1948.
To eliminate the possibility of a short circuit occurring between the battery terminal bases and the battery box, a wood filler block 1/4 inch x 1 1/2 inches x 10 inches (Piper P/N 11367) should be fastened to the upper inside edge of the battery box with two No. 6-32 x 1/2 flat head machine screws. Any insulating spacer which will accomplish this same objective may also be used. On completion of this change appropriate entry shall be made in the aircraft log book.
If the Reading R24L Battery has been replaced with an S24 Battery and proper spacer channels (Piper P/N 10926 and 10927) are installed, the above changeis unnecessary.
(Piper Service Bulletin No. 98 dated July 28, 1947, covers this same subject.)
